Built from micrograin solid carbide, it delivers the rigidity and edge retention needed for tight-tolerance work in steel and stainless steel. The bar features a 5.00 mm minimum bore diameter, a 5.00 mm shank diameter, and a maximum bore depth of 35.00 mm, making it well suited for deep, narrow bore applications where tool deflection and surface finish are critical. With a 0.15 mm corner radius and a right-hand cutting direction, the TKB03013 is intended for CNC turning centers and boring machines operated by machinists and toolroom professionals.\u003c\/p\u003e\n\u003cp\u003eThis micro boring bar is used in precision machining environments where small internal diameters require consistent chip control and dimensional accuracy. Its primary workpiece material is steel, with a secondary rating for stainless steel, covering a broad range of common production and job-shop applications. The EZB series designation indicates compatibility with standard micro boring bar setups. At 58.10 mm overall length, it fits compact tooling systems on CNC lathes and small-bore turning applications in both production and prototype environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for high wear resistance and edge stability\u003c\/li\u003e\n  \u003cli\u003e5.00 mm minimum bore diameter suits tight internal bore requirements\u003c\/li\u003e\n  \u003cli\u003e35.00 mm maximum bore depth supports deeper internal features without tool change\u003c\/li\u003e\n  \u003cli\u003e0.15 mm corner radius provides fine surface finish on small bores\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for standard CNC turning center setups\u003c\/li\u003e\n  \u003cli\u003e95-degree bar end angle for clearance in confined bore geometries\u003c\/li\u003e\n  \u003cli\u003eRated for steel and stainless steel workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option within the KYOCERA EZB series micro boring bar lineup, suitable for use in CNC turning centers and small-bore boring machines accepting a 5.00 mm shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and locked out before mounting or removing boring bars. Secure the shank in a compatible tool holder to the holder manufacturer's specified clamping procedure, confirming proper overhang does not exceed the rated maximum bore depth. Verify cutting direction and tool offset settings in the CNC program before initiating the first cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 5.00 mm (0.1969 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 35.00 mm (0.9843 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 58.10 mm (2.2874 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.15 mm (0.0059 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBar End Angle\u003c\/strong\u003e: 95 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Micrograin Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: EZB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241601\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KYOCERA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TKB03013\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA","offers":[{"title":"Default Title","offer_id":51744470958386,"sku":"TKB03013","price":87.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ecd456c38f3970f24274732d6c42b6fc.jpg?v=1788856972","url":"https:\/\/voomisupply.com\/products\/kyocera-tkb03013-micro-boring-bar-5mm-ezb-series","provider":"Voomi Supply","version":"1.0","type":"link"}
